DNA replication in bacteria occurs (a) during S-phase (b) within nucleolus (c) prior to fission (d) just before transcription?

Question

Answer

A

Answer

During  s-phase, is right answer....,,,!!!'

Answer

Answer is (c) prior to fission. in bacteria though true sexual reproduction is not there , they usually reproduce by asexual methods like binary fission. and the binary fission in bacteria is carried out by 3steps.1)replication of DNA 2) mesosome division & membrane formation 3) cross wall formation.
good luck!

Answer

Prior to fission

Answer

Prior to fission becoz bacteria does not show well s phase due to their primitive nature.

Answer

During s-phase

Answer

Correct anwser is s phase

Answer

Prior to fission

Answer

During S phase

Answer

DNA replication in bacteria

Introduction
DNA replication is the process by which a cell duplicates its DNA in order to pass on genetic information to its daughter cells during cell division. In bacteria, DNA replication occurs prior to cell division and is a vital process to ensure the accurate transmission of genetic material to the next generation.

Timing of DNA replication
DNA replication in bacteria does not occur during a specific phase of the cell cycle, as seen in eukaryotic cells. Instead, it is a continuous process that takes place throughout the entire cell cycle. This is because bacteria lack a defined S-phase, as observed in eukaryotes, where DNA replication predominantly occurs.

Location of DNA replication
DNA replication in bacteria does not occur within the nucleolus, as the nucleolus is a distinct structure found within the nucleus of eukaryotic cells. In bacteria, DNA replication takes place within the cytoplasm, as bacteria lack a nucleus. The replication machinery, including enzymes and proteins necessary for DNA synthesis, is present in the cytoplasm of bacteria.

Relation to fission
DNA replication in bacteria occurs prior to the process of fission, which is the asexual reproduction method in bacteria. Fission involves the division of a bacterial cell into two daughter cells. Before fission, the bacterial cell must replicate its DNA to ensure that each daughter cell receives a complete copy of the genetic material. This replication ensures that the genetic information is transmitted accurately to the next generation of bacteria.

Relation to transcription
DNA replication in bacteria occurs just before transcription. Transcription is the process by which the genetic information encoded in DNA is transcribed into RNA molecules. During DNA replication, the DNA strands are unwound, and each strand serves as a template for the synthesis of a new complementary strand. Once DNA replication is complete, the newly formed DNA molecules can serve as templates for transcription, where RNA molecules are synthesized using the DNA template.

Conclusion
In conclusion, DNA replication in bacteria occurs continuously throughout the cell cycle, prior to fission, and just before the process of transcription. It takes place within the cytoplasm of bacteria, as bacteria lack a nucleus. This process ensures the accurate transmission of genetic material to the next generation of bacteria and is essential for the proper functioning and survival of bacterial cells.
